Title: Laser guided moving screen display
Inventor: TULI RAJA S
IPC: G09F19/12
Filed: 1992-08-13
Abstract: ABSTRACT:          A computer/microprocessor guided laser beam is to be used to address heat or ultraviolet light (or other frequencies of electromagnetic waves) sensitive pixels on a display board, thus creating a moving display. The speed at which a laser can be made to traverse would make this display extremely fast, even capable of Video/Television projection. Uses of this display would be numerous as it possesses superior performance at a lower cost than conventional display systems. Moving LED displays are difficult to read in daylight, in direct sunlight, or indoors. Flip-disk technology is an alternative to LEDs, but each disk requires its own electromagnet, further increasing the cost, as each electromagnet has to be individually addressed. Laser guided displays will be much faster, posses higher resolution and considerably cheaper than conventional displays, especially as size and resolution increase.

Title: Liquid-vapour contact columns
Inventor: BIDDULPH MICHAEL W
IPC: B01D3/20
Filed: 1992-11-12
Abstract: ABSTRACT LIQUID-VAPOUR CONTACT COLUMNS            A liquid-vapour contact column includes an array of vertically spaced horizontal liquid-vapour contact trays having generally circumferential sides and arrangement of downcomers to conduct liquid from each tray in the array to the tray below.  Each tray has gas passages to enable gas to pass into contact with the liquid.  A weir 46 is disposed on the floor of at least one downcomer.  Each side of the weir 46 is spaced from the corresponding side of the downcomer.  This arrangement counteracts a tendency for liquid flowing along the floor of the downcomer to become detached from the sides of the downcomer, such detachment leading to maldistribution of liquid on the tray and hence to less efficient operation of the column.

Title: Sensor detection signal extracting circuit
Inventor: TATEISHI TETUO
IPC: G01D3/036
Filed: 1993-01-07
Abstract: Abstract A sensor detection signal extracting circuit comprises a sensor, a control voltage generator, an adder, an amplifier, and a low-pass filter.  The control voltage generator comprises two input terminals to one of which a voltage is applied based on the voltage source of the sensor.  The output of the control voltage generator is added to the output of the sensor by the adder.  The output of the adder is amplified by the amplifier, and its output is outputted to the output terminal and applied to the other input terminal of the control voltage generator through the low-pass filter.  As a result, two loop systems are formed, that is, one loop for offsetting the change in a voltage of a voltage source applied to the sensor, and the other loop for offsetting a change of  low  frequency  such  as  the  environmental temperature. Therefore, the true output of the sensor can be obtained at the output terminal with little effect by the voltage change of the voltage source or by change in temperature.

Title: Mine roof bolt
Inventor: GILLESPIE HARVEY D
IPC: E21D21/00
Filed: 1993-03-15
Abstract: An improved mine roof bolt is constructed of pre-tensioned, multi-strand steel cable.   The bolt head is constructed of a hexagonal-or other drive-headed collar having an internally tapered frusto-conical bore therethrough,  and a tapered plug having a frusto-conical outer surface that engages the frusto-conical inner surface of the drive collar.  The tapered plug has an internal bore essentially concentric with the outer frusto-conical surface, and is  adapted  to  fit  over  the multi-stranded  steel  cable,  the hexagonal head drive collar fitting over the tapered plug such that pressing the tapered plug and steel cable into the inner frusto-conical bore of the hexagonal-head drive collar causes serrations on the internal bore of the tapered plug to be urged down against, and bite into, the steel cable, resulting in a solid hexagonal head for the cable bolt.  The tapered plug is in actuality, a pair of essentially identical diametrically opposed semi-frusto-conical tapered sections that more easily compress together to bite into the multi-strand steel cable.   The improved mine roof bolt is intended for use in passive-type mine roof systems.

Title: Bone screw with improved threads
Inventor: LASNER JEFFREY
IPC: F16B33/02
Filed: 1991-11-26
Abstract: A bone screw (10) having a helical thread that gradually increases in thickness from the tip (14) to the head (11) of the screw.  The thin thread at the tip of the screw can be inserted into a bone with minimal tearing or cracking of the bone. The thicker treads ascending from the tip to the head of the screw displaces bone against the superior (top) thread surfaces (17). This displacement of bone increases the screw's resistance to being pulled-out of the bone. The thicker core just below the screw head increases the screw's ability to withstand compressive and distractive loads. The core (12) is thickest just below the head because it is at that point on the screw that the fulcrum loads are greatest.

Title: Pixel control circuitry for spatial light modulator
Inventor: KORNHER KEVIN L
IPC: H04B10/118
Filed: 1994-01-11
Abstract: A spatial light modulator (10) having reduced control circuitry as compared to existing devices. Sets of pixel elements (11) share a memory cell (12), such that each memory cell (12) has the same fanout as other memory cells (12). Each pixel element (11) in a set is switched to an on or off state via a reset line (13) that is separate from that of the other pixel elements (11) in that set. Frame data is loaded in split bit-frames during a set time period, such that each split bit-frame contains only the data for pixel elements (11) on one reset line (13). Thus, the same memory cell (12) can be used to deliver data to all pixel elements (11) in its fanout because only one pixel element (11) in the fanout is switched at a time.
